A pulsar is generally believed to be a rapidly rotating neutron star that emits pulses of radiation (such as x-rays and radio waves) at known regular intervals. A pulsar (from pulse and -ar as in quasar) is a highly magnetized rotating compact star (usually neutron stars but also white dwarfs) that emits beams of electromagnetic radiation out of its magnetic poles. This recording This is the fastest known pulsar, rotating with a period of 0.00155780644887275 seconds, or about 642 times a second.
